[78-L] Flexo Record questions

I think the compliance of the reproducer should be uniform throughout the side of the record, but your comment about the position of the reroducer on the surface of the disc is right on - what is known as inner groove distortion, caused by the relatively slow speed of the disc surface under the stylus compared to the beginning of the record. Another factor to consider is the lack of modulation in the run-off spiral. The stresses on the playback stylus from musical areas of the record which cause the wear on the stylus are completely absent in the run-off groove, so like the groove on an Edison vertical cut record the geometry of the run-off groove never varies. I have a 1917 Edison phonograph, (Edison called his disc players "phonographs", not gramophones), and it still has its original playback stylus and I had it checked recently by Bob Nix, the phonograph Doctor, and it's still in like new condition.
